India's Reservoirs Hit 10-Year Low Amid Monsoon Woes
30 Sep
Summary
- Reservoir water storage is at 70% of capacity, a 10-year low.
- El Nino phenomenon is causing erratic rainfall and dry spells.
- South India faces the most severe water reserves deficit this year.
As India's monsoon season nears its end on September 30, 2026, water storage in 178 national reservoirs stands at a concerning 70% of capacity. This level is below the decadal average and marks a 10-year low, coinciding with drought declarations in Maharashtra and Karnataka. The Central Water Commission (CWC) report highlights a particularly grim situation in southern India, which holds the lowest water reserves this year. Northern India has also seen a significant drop in water reserves, plummeting from 92.3% to 62% of total storage capacity.
The primary driver for this depletion is the El Nino phenomenon, which has caused erratic rainfall and above-normal temperatures. Since late August, strengthening El Nino conditions have been linked to a rainfall deficit, with India receiving 12% less rainfall than normal as of September 28, 2026. With little hope for significant improvement before the monsoon exits, concerns about India's water security are escalating.
Globally, freshwater is scarce, with only 2.5% of Earth's water being freshwater, much of which is locked in glaciers and ice caps. India, supporting 18% of the world's population, relies on only 4% of global freshwater resources. Per capita water availability in India has drastically decreased from 5,177 m³ in 1951 to a projected 1,367 m³ by 2031. This trend indicates a severe water stress situation, with many areas already facing scarcity and over-exploitation of groundwater resources.
